Expert Tip #1: Mastering Proper Chainsaw Safety and Maintenance

Before even thinking about cutting, safety must be your top priority. Chainsaw accidents can be devastating, so a thorough understanding of safety protocols is non-negotiable. Furthermore, a well-maintained chainsaw operates more efficiently, consuming less fuel and delivering cleaner cuts, ultimately saving you money and time.

Safety Gear: Your First Line of Defense

Helmet: Protects your head from falling branches and kickback. I always recommend a helmet with a face shield and ear protection.
Eye Protection: Even with a face shield, safety glasses are a must. Debris can still find its way in.
Hearing Protection: Prolonged exposure to chainsaw noise can cause permanent hearing damage. Earplugs or earmuffs are essential.
Gloves: Provide a secure grip and protect your hands from cuts and abrasions.
Chainsaw Chaps: These are critical for leg protection. The ballistic nylon fibers are designed to stop a moving chain.
Steel-Toed Boots: Protect your feet from falling logs and potential chainsaw mishaps.

I remember one time I skipped wearing my chaps for a “quick” cut. A moment of carelessness almost cost me dearly. A small kickback resulted in the chain grazing my leg. Thankfully, it only nicked my jeans, but it was a stark reminder that complacency can lead to serious injury.

Regular Maintenance: Keeping Your Chainsaw in Top Shape

Chain Sharpening: A sharp chain cuts faster and more efficiently, reducing strain on the engine and minimizing kickback. I sharpen my chain after every few uses, or whenever I notice it’s not cutting as smoothly.
- Cost of Chain Sharpening: Expect to pay around \$10-\$20 for professional chain sharpening. However, learning to do it yourself is a valuable skill that will save you money in the long run. Chainsaw sharpening kits typically cost between \$20 and \$50.
Air Filter Cleaning: A dirty air filter restricts airflow, causing the engine to run rich and consume more fuel. Clean the air filter regularly, especially when working in dusty conditions.
Spark Plug Inspection: A fouled spark plug can cause starting problems and poor engine performance. Inspect the spark plug regularly and replace it as needed. Spark plugs are relatively inexpensive, typically costing around \$5-\$10.
Bar and Chain Lubrication: Proper lubrication is essential for extending the life of the bar and chain. Check the oil level frequently and use a high-quality bar and chain oil.
- Cost of Bar and Chain Oil: A gallon of bar and chain oil typically costs between \$10 and \$20.
Chain Tension Adjustment: A properly tensioned chain cuts more efficiently and reduces the risk of derailment. Check the chain tension before each use and adjust as needed.
Fuel Mixture: Use the correct fuel mixture as specified by the manufacturer (usually a 50:1 ratio of gasoline to two-stroke oil). Using the wrong fuel mixture can damage the engine.
- Cost of Two-Stroke Oil: A small bottle of two-stroke oil (enough for a few gallons of fuel) typically costs around \$5-\$10.

By investing in proper safety gear and maintaining your chainsaw regularly, you’ll not only protect yourself from injury but also ensure that your Stihl MS 170 operates at peak efficiency, saving you time, money, and energy.

Expert Tip #2: Choosing the Right Wood and Understanding its Properties

The type of wood you’re cutting significantly impacts the effort required and the longevity of your chainsaw. Understanding wood density, grain patterns, and moisture content is crucial for achieving clean, efficient cuts.

Hardwoods vs. Softwoods: A Matter of Density

Hardwoods: These are generally denser and more difficult to cut than softwoods. Examples include oak, maple, and hickory. Cutting hardwoods requires a sharper chain and more power.
Softwoods: These are less dense and easier to cut. Examples include pine, fir, and cedar. The Stihl MS 170 is well-suited for cutting softwoods.

Trying to force the MS 170 through a large piece of hardwood will not only result in a poor cut but also put unnecessary strain on the engine and chain. It’s like trying to cut butter with a dull knife – it’s frustrating and inefficient.

The Impact of Moisture Content

Green Wood: Freshly cut wood has a high moisture content, making it heavier and more difficult to cut. The chain can also bind more easily.
Dry Wood: Seasoned wood (wood that has been allowed to dry) is easier to cut and less likely to bind.

I once tried to cut a large oak log that had just been felled. The chain kept binding, and the engine struggled to maintain power. After letting the log dry for a few months, it was significantly easier to cut.

Understanding Wood Grain

The direction of the wood grain also affects the cutting process. Cutting with the grain is generally easier than cutting against it. Pay attention to the grain pattern and adjust your cutting technique accordingly.

Cost Considerations: Buying vs. Harvesting Your Own Wood

Buying Firewood: The cost of firewood varies depending on location, wood type, and quantity.
- Average Price per Cord: According to recent data, the average price of a cord of firewood in the US ranges from \$150 to \$400, depending on the region and wood type. Hardwoods like oak and maple typically command a higher price than softwoods like pine.
- Cost per Bundle: Smaller bundles of firewood typically cost between \$5 and \$10.
Harvesting Your Own Wood: If you have access to land and the necessary permits, harvesting your own wood can be a cost-effective option. However, you’ll need to factor in the cost of fuel, bar and chain oil, and your time.
- Permit Costs: Depending on your location, you may need to obtain a permit to harvest wood from public lands. Permit costs vary widely, ranging from a few dollars to several hundred dollars per year.

By understanding the properties of different types of wood and considering the costs associated with buying vs. harvesting your own wood, you can make informed decisions that will save you time, energy, and money.

Expert Tip #3: Mastering Cutting Techniques for Efficiency and Precision

Proper cutting techniques are essential for achieving perfect cuts with the Stihl MS 170. This not only ensures a clean and professional finish but also minimizes strain on the chainsaw and reduces the risk of kickback.

The Bore Cut: A Technique for Felling Small Trees

The bore cut is a technique used to fell small trees safely and efficiently. It involves boring into the tree trunk with the tip of the chainsaw bar to create a hinge that controls the direction of the fall.

Assess the Tree: Before making any cuts, assess the tree for lean, wind direction, and any potential hazards.
Make the Face Cut: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
Make the Bore Cut: Carefully insert the tip of the chainsaw bar into the tree trunk behind the notch.
Create the Hinge: Leave a hinge of uncut wood to control the fall of the tree.
Make the Back Cut: Cut through the remaining wood from the back of the tree towards the hinge.
Retreat Safely: As the tree begins to fall, retreat quickly and safely away from the falling tree.

The Limbing Technique: Removing Branches Safely

Limbing is the process of removing branches from a felled tree. It’s important to use proper limbing techniques to avoid kickback and other hazards.

Work from the Base to the Tip: Start at the base of the tree and work your way towards the tip.
Cut on the Upside of the Branch: When cutting branches, cut on the upside of the branch to avoid pinching the chain.
Use a Stable Stance: Maintain a stable stance and keep both feet firmly planted on the ground.
Avoid Cutting Above Shoulder Height: Cutting above shoulder height can be dangerous and tiring.

The Bucking Technique: Cutting Logs into Lengths

Bucking is the process of cutting logs into desired lengths. It’s important to use proper bucking techniques to avoid pinching the chain and creating uneven cuts.

Support the Log: Before making any cuts, make sure the log is properly supported to prevent it from rolling or shifting.
Cut from the Top Down: When cutting logs, cut from the top down to avoid pinching the chain.
Use a Sawhorse: Using a sawhorse can make bucking easier and safer.
- Cost of a Sawhorse: A basic sawhorse typically costs between \$20 and \$50.

I remember trying to buck a log without properly supporting it. The log rolled, pinching the chain and nearly causing a kickback. It was a valuable lesson in the importance of proper technique.

Minimizing Kickback: A Critical Safety Consideration

Kickback is a dangerous phenomenon that occurs when the tip of the chainsaw bar comes into contact with a solid object, causing the chainsaw to suddenly jump back towards the operator. To minimize the risk of kickback:

Use a Chainsaw with a Chain Brake: A chain brake is a safety device that stops the chain from rotating in the event of kickback.
Maintain a Sharp Chain: A dull chain is more likely to cause kickback.
Avoid Cutting with the Tip of the Bar: Be aware of the position of the tip of the bar and avoid contacting solid objects with it.
Maintain a Firm Grip: Maintain a firm grip on the chainsaw with both hands.
Stand to the Side of the Cut: Avoid standing directly behind the chainsaw when cutting.

By mastering these cutting techniques and taking precautions to minimize the risk of kickback, you can achieve perfect cuts with the Stihl MS 170 safely and efficiently.

Calculating the Cost per Cord of Firewood

If you’re preparing firewood, it’s helpful to calculate the cost per cord. This will allow you to compare your costs to the market price of firewood and determine whether you’re saving money by preparing your own firewood.

Calculate Total Costs: Add up all of the costs associated with preparing a cord of firewood, including the cost of wood, fuel, maintenance, and labor.
Divide by the Number of Cords: Divide the total costs by the number of cords of firewood you’re preparing.

For example, if you spend \$200 on wood, \$20 on fuel, \$10 on maintenance, and \$50 on labor to prepare one cord of firewood, your total costs would be \$280. Dividing this by one cord gives you a cost of \$280 per cord.

Case Study: Budgeting for a Firewood Project

Let’s consider a case study of a homeowner who wants to prepare 5 cords of firewood for the winter.

Wood: The homeowner purchases 5 cords of mixed hardwoods for \$250 per cord, for a total cost of \$1250.
Fuel: The homeowner estimates that they’ll use 10 gallons of fuel at \$3.50 per gallon, for a total cost of \$35.
Maintenance: The homeowner estimates that they’ll spend \$20 on chain sharpening and \$10 on bar and chain oil, for a total cost of \$30.
Labor: The homeowner estimates that it will take them 20 hours to prepare the firewood and values their time at \$15 per hour, for a total cost of \$300.

The total cost of the project is \$1250 + \$35 + \$30 + \$300 = \$1615. The cost per cord is \$1615 / 5 = \$323.

By comparing this cost to the market price of firewood in their area, the homeowner can determine whether it’s more cost-effective to prepare their own firewood or purchase it from a supplier.

By implementing these budgeting and cost management strategies, you can effectively manage the financial aspects of your wood processing or firewood preparation projects and ensure that they stay within your budget.
